I'd like to install solar window film on a west side window to reduce heating in that room. It's a double hung single pane window with a storm window. About a 3" gap. I could put it on the regular window or the storm window. I was thinking storm window. Pros or Cons of either installation? Thanks.

Check window warranty to make sure that you do not void warranty with window film. Also discuss this problem with the window film manufacturer. Awnings, solar shades, blinds, insulated window treatments, and other options are available.

 

I'm thinking of a similar installation, but I've heard that solar film can cause some windows to crack due to increased heat. What did you learn? Did you install the film?
